Canon City

At the Colorado State Penitentiary, inmates Carl Schwartzmiller (Jeff Corey) and Jim Sherbondy (Scott Brady) conceive a daring prison break. While a group of prisoners subdue a guard and take him hostage, Carl and Jim, along with 10 others, make their escape to nearby Canon City, Colo. As the fugitives terrorize residents of the city, taking local families hostage in their own homes, Warden Roy Best (Roy Best) devises a plan to get the prisoners back -- dead or alive.
